help with arithmetic overflow error with insted of update trigger

Hi, I have a view set up with an INSTEAD OF UPDATE trigger specified.
When I perform an update on certain records, i.e.:
UPDATE mytableview
SET field1 = 1
WHERE userid = 1234
I am finding that *some* user id's result in the follwing error:
"Arithmetic overflow error converting expression to data type smalldatetime.
The statement has been terminated."
mytable view has a number of data fileds. All the data fields are of type
smalldatatime.
When i compare the user record of a userid that causes an error to one that
doesnt cause an error, the dates do vary, where some date fields have NULL's
or correctly formated smalldatatime values (yes I know about the restriction
of smalldatetime to range between 1900 and 2079).
The odd thing is that even if i am updating a non-date field within the
view, the above arithmetic error still occurs.
My trigger looks like the following:
CREATE TRIGGER mytrigger ON mytableview
INSTEAD OF UPDATE
AS
DECLARE @.mydate datetime
SELECT @.mydate = GETDATE()
UPDATE mytable SET
field1 = ISNULL(inserted.field1, 0),
field2 = ISNULL(inserted.field2, 0),
field3 = ISNULL(inserted.field3, 0),
date1 = inserted.date1,
date2 = @.date+30
FROM inserted
WHERE mytable.userid = inserted.userid
Am i getting this error because i am mixing a date2 fiels (which is of type
smalldatetime) with @.date (which is of type datetime) ?
Any help most appreciated.Do you need the extra ms or time range? If not try:
DECLARE @.mydate smalldatetime
SELECT @.mydate = GETDATE()
SELECT @.mydate

I hope its as obvious as changing smalldatetime to datetime!
